The weakness on pure metals is not knowing the exact supply. It seems like the method they were able to use to get us off those standards was by both having a very significant initial amount in hand, and leveraging that + legislation/bribes/threats/assassinations to defeat price discovery in the largest markets and further consolidate control.

The advantage of having Bitcoin on top of that is being able to leverage it to validate actual available amounts. Perhaps gold and silver could be verified and coated with an NFT as part of its trade protocol in such a way that anyone could verify it and know it’s legitimate using a fairly inexpensive machine.

Bitcoin would need to have a LOT of nodes taken out and corrupted simultaneously in order to take out the whole network.

It seems like a good security measure, though as with all things, having multiple options to back work with energy is better than having one. Maximal distributed points of failure that can all fail independently without taking down the whole grid.

And if its network is hosted and backed up in space… then so long as space is protected by say.. a Space Force, it could be very, very tricky to take the whole thing down or corrupt it. It would make it harder to steal large amounts of metals, as their owner would be known. It would make it hard to corruptly spend many types (not all) of currency. You would be able to “upload” your gold to Bitcoin, and spend it in another country, without needing to carry around the weight and risk losing it in an accident.

And there are always offline cold storage Bitcoin wallets. Lots of good options presented.
